Description
The AT49BV/LV040(T) are 3-volt only, 4-megabit Flash memories organized as
524,288 words of 8-bits each. Manufactured with Atmel’s advanced nonvolatile CMOS
technology, the devices offer access times to 70 ns with power dissipation of just
90 mW over the commercial temperature range. When the device is deselected, the
CMOS standby current is less than 50 µA.

The device contains a user-enabled “boot block” protection feature. Two versions of
the feature are available: the AT49BV/LV040 locates the boot block at lowest order
addresses (“bottom boot”); the AT49BV/LV040T locates it at highest order addresses
(“top boot”).

To allow for simple in-system reprogrammability, the
AT49BV/LV040(T) does not require high input voltages for
programming. Three-volt-only commands determine the
read and programming operation of the device. Reading
data out of the device is similar to reading from an EPROM.
Reprogramming the AT49BV/LV040(T) is performed by
erasing the entire four megabits of memory and then pro-
gramming on a byte-by-byte basis. The typical byte
programming time is a fast 30 µs. The end of a program
cycle can be optionally detected by the Data Polling
feature. Once the end of a byte program cycle has been
detected, a new access for a read or program can begin.
The typical number of program and erase cycles is in
excess of 10,000 cycles.
The optional 16K bytes boot block section includes a repro-
gramming write lockout feature to provide data integrity.
The boot sector is designed to contain user-secure code,
and when the feature is enabled, the boot sector is perma-
nently protected from being reprogrammed.

Device Operation
READ: The AT49BV/LV040(T) is accessed like an
EPROM. When CE and OE are low and WE is high, the
data stored at the memory location determined by the
address pins is asserted on the outputs. The outputs are
put in the high-impedance state whenever CE or OE is
high. This dual-line control gives designers flexibility in pre-
venting bus contention.
BYTE PROGRAMMING: Once the memory array is
erased, the device is programmed (to a logical “0”) on a
byte-by-byte basis. Please note that a data “0” cannot be
programmed back to a “1”; only erase operations can con-
vert “0”s to “1”s. Programming is accomplished via the
internal device command register and is a four-bus cycle
operation (please refer to the Command Definitions table).
The device will automatically generate the required internal
program pulses.
ERASURE: Before a byte can be reprogrammed, the 512K
bytes memory array (or 496K bytes if the boot block fea-
tured is used) must be erased. The erased state of the
memory bits is a logical “1”. The entire device can be
erased at one time by using a six-byte software code. The
software chip erase code consists of six-byte load com-
mands to specific address locations with a specific data
pattern (please refer to “Chip Erase Cycle Waveforms” on
page 8).
The program cycle has addresses latched on the falling
edge of WE or CE, whichever occurs last, and the data
latched on the rising edge of WE or CE, whichever occurs
first. Programming is completed after the specified tBP cycle
time. The Data Polling feature may also be used to indicate
the end of a program cycle.
BOOT BLOCK PROGRAMMING LOCKOUT: The device
has one designated block that has a programming lockout
feature. This feature prevents programming of data in the
designated block once the feature has been enabled. The
size of the block is 16K bytes. This block, referred to as the
boot block, can contain secure code that is used to bring up
the system. Enabling the lockout feature will allow the boot
After the software chip erase has been initiated, the device
will internally time the erase operation so that no external
clocks are required. The maximum time needed to erase
the whole chip is tEC. If the boot block lockout feature has
been enabled, the data in the boot sector will not be
erased.

code to stay in the device while data in the rest of the
device is updated. This feature does not have to be acti-
vated; the boot block’s usage as a write-protected region is
optional to the user. The address range of the
AT49BV/LV040 boot block is 00000H to 03FFFH, while the
address range of the AT49BV/LV040T boot block is
7C000H to 7FFFFH.
For details, see “Operating Modes” on page 5 (for hard-
ware operation) or “Software Product Identification
Entry/Exit” on page 10. The manufacturer and device
codes are the same for both modes.
DATA POLLING: The AT49BV/LV040(T) features Data
Polling to indicate the end of a program cycle. During a pro-
gram cycle, an attempted read of the last byte loaded will
result in the complement of the loaded data on I/O7. Once
the program cycle has been completed, true data is valid
on all outputs and the next cycle may begin. Data Polling
may begin at any time during the program cycle.
Once the feature is enabled, the data in the boot block can
no longer be erased or programmed. Data in the main
memory block can still be changed through the regular pro-
gramming method. To activate the lockout feature, a series
of six program commands to specific addresses with spe-
cific data must be performed. Please refer to the Command
Definitions table.
TOGGLE BIT: In addition to Data Polling, the
AT49BV/LV040(T) provides another method for determin-
ing the end of a program or erase cycle. During a program
or erase operation, successive attempts to read data from
the device will result in I/O6 toggling between one and
zero. Once the program cycle has completed, I/O6 will stop
toggling and valid data will be read. Examining the toggle
bit may begin at any time during a program cycle.
BOOT BLOCK LOCKOUT DETECTION: A software
method is available to determine if programming of the boot
block section is locked out. When the device is in the soft-
ware product identification mode (see Software Product
Identification Entry and Exit sections) a read from address
location 00002H will show if programming the boot block is
locked out for the AT49BV/LV040 and a read from address
7C002H will show if programming the boot block is locked
out for the AT49BV/LV040(T). If the data on I/O0 is low, the
boot block can be programmed; if the data on I/O0 is high,
the program lockout feature has been activated and the
block cannot be programmed. The software product identi-
fication code should be used to return to standard
operation.
HARDWARE DATA PROTECTION: The Hardware Data
Protection feature protects against inadvertent programs to
the AT49BV/LV040(T) in the following ways: (a) VCC sense:
if VCC is below 1.8V (typical), the program function is inhib-
ited. (b) Program inhibit: holding any one of OE low, CE
high or WE high inhibits program cycles. (c) Noise filter:
pulses of less than 15 ns (typical) on the WE or CE inputs
will not initiate a program cycle.
INPUT LEVELS: While operating with a 2.7V to 3.6V
power supply, the address inputs and control inputs (OE,
CE and WE) may be driven from 0 to 5.5V without
adversely affecting the operation of the device. The I/O
lines can only be driven from 0 to VCC + 0.6V.
PRODUCT IDENTIFICATION: The product identification
mode identifies the device and manufacturer as Atmel.
It may be accessed by hardware or software operation. The
hardware operation mode can be used by an external pro-
grammer to identify the correct programming algorithm for
the Atmel product.
